Final answer:

Bases are substances that contain or produce hydroxide ions. Strong bases completely dissociate in water. Arrhenius bases follow a specific naming pattern.


Explanation:

Bases are substances that contain hydroxide ions (OH-) or produce hydroxide ions when dissolved in water. Strong bases, such as NaOH (sodium hydroxide), KOH (potassium hydroxide), and Ca(OH)2 (calcium hydroxide), completely dissociate in water to release hydroxide ions. The naming of Arrhenius bases follows the pattern of starting with the metal name followed by 'hydroxide,' like NaOH as sodium hydroxide.
